The present invention discloses a living-body detection based anti-cheating online research method, device and system. The method comprises the following steps: a model establishment step of establishing an action recognition model base; an information acquisition step of acquiring action recognition information about a user, the action recognition information comprising a current feature vector of a human face; and a feature comparison step of comparing the action recognition information about the user to a verification feature vector in the action recognition model base, the verification being passed if a comparison result indicates consistency. In the present invention, human facial recognition is introduced to an online questionnaire research system to conduct living-body detection; by adding a user verification link in which a facial action is completed as prompted, combined with the living-body detection technique, the validity and authenticity of questionnaire sample data is improved. |
